Method and System for Indicating Transmission Parameter

An evolved node B for indicating a transmission parameter, comprising hardware performing instructions stored in a non-transitory computer readable medium which executes steps in a multiple user multi-input multi-output (MIMO) data downlink transmission module,

• the MIMO data downlink transmission module is configured to:
• when MIMO data are transmitted, use a newly-added indication signaling in a downlink control information format to indicate joint encoded parameters;
• wherein, when a value of the newly-added indication signaling for a case that a single transport block is enabled, is same with a value of the newly-added indication signaling for a case that two transport blocks are enabled, the joint encoded parameters are different, the same value of the newly-added indication signaling refers to different settings on the following one or more joint encoded parameters comprising:
• a number of transmitted layers,
• scrambling identity (SCID),
• antenna port,
• spreading code information,
• reference signal information;
• wherein, when a single transport block is enabled, for part of values of the newly-added indication signaling, the scrambling identity as one of the joint encoded parameter is encoded;
• when two transport blocks are enabled, for part of the values of the newly-added indication signaling, the scrambling identity as one of the joint encoded parameter is encoded.
